南京市沿山大道下穿林浦铁路工程接触网过渡方案研究

Research on Overhead Contact System Transition Scheme of Nanjing Yanshan Avenue under Linpu Railway Project

南京市沿山大道为新建城市主干路,计划行车速度为60km/h,与林浦铁路产生交叉,交叉里程为K0+854.692~K0+886.192,新建公路同时下穿林浦铁路上、下行线及林浦铁路三线。因下穿铁路的多个框架桥并行,且框架桥双侧涉及改移燃气管道及排水涵,对铁路接触网造成较大影响。本文根据桥梁改造实施步骤,研究接触网过渡方案,确保桥梁实行过程中及实行后,铁路接触网正常运行。

Yanshan Avenue in Nanjing is a new urban trunk road with a planned speed of 60km/h.It will cross with Linpu Railway,and the crossing mileage is K0+854.692~K0+886.192.The new highway will pass through the upper and lower lines of Linpu Railway and the third line of Linpu Railway at the same time.Due to the parallel of several frame Bridges under the railway,and the two sides of the frame bridge are involved in shifting gas pipelines and drainage culverts,the railway OCS has a great impact.According to the implementation steps of bridge reconstruction,this paper studies the OCS transition scheme to ensure the normal operation of railway OCS during and after bridge implementation.
